The invention relates to compounds that act in combination with antimicrobial agents to enhance their potency, in particular inhibitors of microbial efflux pumps and use of these compounds in combination with antimicrobial compounds, in particular antibiotics, for treatment of bacterial and other microbial diseases. Antibiotics are important and effective drugs to treat bacterial infections in many clinical settings. The introduction of antibiotics to treat infectious diseases greatly improved public health in the twentieth century. Early on, bacteria started to develop resistance mechanisms to evade the action of antibacterial agents. The widespread use of various antibacterial agents promoted the evolution of multi-drug resistant pathogens and their global spread. Nowadays, increased occurrence of resistant pathogens, especially in hospitals and care centers, causes problems for the treatment of infections and leads to higher morbidity and mortality, longer treatment durations and increased costs (e.g. Gootz T. D. 2010. Critical Rev. Immunol. 30(1):79-93; Silver L. L. 2011. Clin. Microbiol. Rev. 24(1): 71-109; Denis G. A. and Relich R. F. Clin Lab Med 2014. 34: 257-270).

Bacteria achieve resistance by different mechanisms. Some mechanisms are specific for a drug or a class of antibiotics whereas other mechanisms are non-specific and affect several unrelated classes of antibiotics. Specific mechanisms can be modification of the drug target or inactivation of the drug by degradation or by enzymatic alteration. Non-specific mechanisms can be reduced uptake of a drug by lower permeability, by transport of drugs out of the bacterial cell or by combinations of both. The result is that drug concentrations that would normally kill bacterial cells are reduced at the target site to levels that allow the survival of the bacteria (Enzyme-Mediated Resistance to Antibiotics. Bonomo R. A. and Tolmasky M. Eds. ASM Press 2007; Martinez and Baquero 2014. Upsala J. Med. Sci. 119: 68-77; Piddock L. J. V. 2006. Clin. Microbiol. Rev. 19(2):382-402; Olivares et al. 2013. Front. Microbiol. 4, 103: doi 10.3389/finicb.2013.00103).

Active transport of antibiotics out of a bacterial cell can confer resistance and contribute significantly to high-level resistances. Multidrug efflux pumps can expel a large variety of chemically different substances including medically important antibiotics and disinfectants. Such systems are perceived as the predominant underlying mechanism of multi-drug resistance in bacteria (e.g. Li et al. 2015. Clin. Microbiol. Rev. 28(2): 337-418; Nikaido 2011. Adv. Enzymol. Relat. Areas Mol. Biol. 77:1-60; Poole 2005. J. Antimicrob. Chemother. 56: 20-51); Olivares et al. 2013. Front. Microbiol. 4:103).

Active drug transporters are divided into two major classes according to their mechanism of energization. Primary transporters like the ABC-type transporters hydrolyze ATP (a primary cellular energy source) to power drug efflux. Most bacterial drug-efflux systems known today belong to the class of secondary transporters using energy stored in the transmembrane electrochemical potential of protons or sodium. Transporters driven by this proton motive force (PMF) can be further divided into four groups based on size as well as structural features. These groups are the major facilitator superfamily (MFS), the small multidrug resistance family (SMR), the resistance nodulation division family (RND), and the multidrug and toxic compound extrusion family (MATE) (for reviews see: Microbial Efflux Pumps Wu, Zhang, Brown Eds. Caister Academic Press 2013; Sun et al. 2014 Biochem. Biophys. Res. Commun. 453(2):254-267). Members of the RND family are highly relevant in terms of multidrug efflux and resistance since they accept a wide variety of substrates. RND pumps are found in Gram-negative bacteria including the clinically relevant Enterobacteriaceae and glucose non-fermenters. Well described members are AcrAB-TolC in Escherichia coli and MexAB-OprM in Pseudomonas aeruginosa. X-ray structures of AcrAB-TolC and MexAB-OprM subunits were the first to be solved and boosted the understanding of the function of tripartite RND pumps (Nikaido H. 2011 Adv. Enzymol. Relat Areas Mol. Biol. 77:1-60; Murakami S. 2008. Curr. Opin. Struct. Biol. 18:459-465; Ruggerone et al. 2013. Curr. Top Med. Chem. 13(24):3079-100). Models for the structure of a complete RND complex were published on the example of AcrAB-TolC and for McxAB-OprM (Kim et al. 2015. Mol. Cells. 38(2): 180-186; Du et al. 2015. Trends Microbiol. 23: 311-319; Du et al. 2014. Nature 509:512-515; Trépout et al. 2010. Biochim. Biophys. Acta 1798: 1953-1960; Symmons et al. 2009. Proc. Natl. Acad. Sci. 106:7173-7178). Pathways for substrate translocation through the assembled pump complex were described on the basis of X-ray crystal structures. Binding sites for a few substrates and inhibitors could be determined and computational simulation were used to describe dynamic interactions of substrates and inhibitors with efflux pumps (reviewed in Yamaguchi et al. 2015. Front Microbiol. 6:327; Ruggerone et al. 2013 Curr. Topics Med. Chem. 13(24):3079-3100).

The expression of RND pumps is regulated in response to environmental stress such as the presence of antibiotics (Morita et al. 2014. Front. Microbiol. 4, 422: doi: 10.3389/finicb.2013.00422; Poole 2014. Can. J. Microbiol. 60:783-791). Enhanced efflux gene expression was found to cause antibiotic resistance. Many antibiotics lack activity against Gram-negative bacteria because of active drug efflux. Overexpression of MexAB-OprM for example, contributes substantially to fluoroquinolone- and 1-lactam-resistance. MexXY, another RND pump from P. aeruginosa, contributes to decreased amikacin susceptibility and co-resistance to fluoroquinolones, carbapenems, and the cephalosporin antibiotic ceftazidime. Reduced or even lost activity due to efflux can be restored by efflux-pump inhibitors. Efflux pumps play a role in biofilm formation, quorum sensing, virulence and invasiveness. Hence, efflux pump inhibitors may be useful to combat several aspects of infections (e.g. Soto S. M. 2013. Virulence 4(3): 223-229; Hirakata et al. 2009. Int. J. Antimicrob. Agents. 34: 343-346).

Increased resistance occurrence and the fact that the number of new antibiotics that are developed dramatically declined in the recent years led to a need for new treatment options. Combination therapy is a proven approach to combat resistant pathogens. Efflux pumps are considered to be targets for inhibitors that can boost the activity of existing antimicrobial agents. Molecules of different sources like natural products (e.g. Piddock L. et al. 2010 J. Antimicrob. Chemother. 65:1215-1223; Starvi et al. 2007 J. Antimicrob. Chemothcr. 59(6): 1247-60; Li et al. 2015. Clin. Microbiol. Rev. 28(2): 337-418), inhibitors of human efflux pumps or new chemical entities were tested and described (reviewed in Van Bambeke et al. 2010. Frontiers in Anti-infective Drug Discovery 1:138-175; Van Bambeke et al. 2006. Recent Patents on Anti-infective Drug Discovery; Zechini B. and Versace I. 2009. 4:37-50; Opperman and Nguyen 2015. Front. Microbiol. 6, 421: doi 10.3389/fmicb.2015.00421). Phenylalanine-arginine beta-naphthylamide (MC-207,110 or PAB3N) from a series of peptidomimetic compounds and the pyridopyrimidine derivative D13-9001 are well studied examples of efflux-pump inhibitors.

is reacted with a compound of formula XIX

to generate a compound of formula IV-7

in which formulae

AR1, AR2, R₁, R₂, R₃, R₅, R₆, R₇ are as in formula I,

When A1 is a halogen atom or a triflate, said compound of formula XVIII can react with a compound of formula XIX wherein A4 a boronic acid, a boronic ester or —SnBu₃ to generate a compound of formula IV-7 wherein L1 is absent.

Following procedures already described in process (a), the compound of formula IV-6 can react with a compound of formula V

R′₄—X  (V)

to generate a compound of formula VI-7

wherein R₄ is as in formula I.

Further coupling with a compound of formula VII, followed by a deprotection step allow the generation of a compound of formula I-10, applying procedures already described in process (a).

Process (h):

This process variant can be used for the manufacture of compounds of formula I as defined above, that present a quaternary amine. These molecules can be obtained by reacting a C1-Co-alkyl halide or the corresponding mesylate, tosylate or triflate with any compound of formula I or VI for which a free secondary amine is present.

The necessary starting materials for the synthetic methods as described herein, if not commercially available, may be made by procedures which are described in the scientific literature, or may be made from commercially available compounds using adaptations of processes reported in the scientific literature. The reader is further referred to Advanced Organic Chemistry, 5th Edition, by J. March and M. Smith, published by John Wiley & Sons, 2001, for general guidance on reaction conditions and reagents.

Furthermore in some of the reactions mentioned herein it may be necessary or desirable to protect any sensitive groups in compounds. Conventional protecting groups may be used in accordance with standard practice (for illustration see Protective Groups in Organic Synthesis, 3^(rd) Edition, by T. W. Greene and P. G. M. Wuts, published by John Wiley & Sons, 1999).

The protecting groups may be removed at any convenient stage in the synthesis using conventional techniques well known in the art, or they may be removed during a later reaction step or work-up.

The compounds of formula I wherein L1 is —(CH₂)_(m)—O—(CH₂)_(n)—, —(CH₂)_(m)—NH—(CH₂)_(n)—, —(CH₂)_(m)—S—(CH₂)_(n)—, —(CH₂)_(m)—SO—(CH₂)_(n)— or —(CH₂)_(m)—SO₂—(CH₂)_(n)—, with m being 1, 2 or 3 and n being 0, 1, 2 or 3 (within the limits defined by the claims), can be obtained as summarized in Scheme 1.

In Scheme 1, all the symbols have the same meanings as previously described in process (a).

When A1 is —NH— and PG1 is an amino protecting group, compounds of formula ITT are usually obtained by reacting the corresponding free amine with allyl, fluorenylmethyl or benzyl chloroformate or with di-tert-butyl dicarbonate in presence of a base such as sodium hydroxide, sodium hydrogencarbonate, triethylamine, 4-dimethylaminopyridine or imidazole. They can also be protected as N-benzyl derivatives by reaction with benzyl bromide or chloride in presence of a base such as sodium carbonate or triethylamine. Alternatively, N-benzyl derivatives can be obtained through reductive amination in presence of benzaldehyde. Further strategies to introduce other amino protecting groups have been described in Protective Groups in Organic Synthesis, 3rd Edition, by T. W. Greene and P. G. M. Wuts, published by John Wiley & Sons, 1999.

Compounds of formula IV-1 (Scheme 1) wherein L1 is —(CH₂)_(m)—O—(CH₂)_(n)— can be obtained from compounds of formula II-1 wherein Y1 is —OH via a Mitsunobu coupling (as reviewed in O. Mitsunobu, Synthesis 1981, 1) with compounds of formula III for which A1-PG1 is a hydroxyl group. The reaction is for example performed in the presence of diethyl or diisopropyl azodicarboxylate and triphenylphosphine, in a wide range of solvents such as N,N-dimethylformamide, tetrahydrofuran, 1,2-dimethoxyethane or dichloromethane and within a wide range of temperatures (between −20° C. and 60° C.). The reaction might also be performed using polymer-supported triphenylphosphine.

An alternative route to form compounds of formula IV-1 wherein L1 is —(CH₂)_(m)—O—(CH₂)_(n)— consists of reacting compounds of formula III wherein A1-PG1 is a hydroxyl group with compounds of formula II-1 for which Y1 is a hydroxyl group, which needs to be activated prior to the reaction as described below, or a halogen atom in presence of an inorganic base such as sodium hydride, potassium carbonate or the like in a solvent such as dichloromethane or N,N-dimethylformamide at a temperature ranging between −20° C. and 80° C. Activation of the hydroxyl group of compounds of formula II-1 wherein Y1 is —OH as for example a mesylate, a tosylate or a triflate can be achieved by reacting the corresponding alcohol with methanesulfonyl chloride or methanesulfonic anhydride, p-toluenesulfonyl chloride, trifluoromethanesulfonyl chloride or trifluoromethanesulfonic anhydride, respectively, in presence of a base such as triethylamine or the like in a dry aprotic solvent such as pyridine, acetonitrile, tetrahydrofuran or dichloromethane between −30° C. and 80° C.

The same procedure can also be applied to generate compounds of formula IV-1 wherein L1 is —(CH₂)_(m)—S—(CH₂)_(n)— or —(CH₂)_(m)—NH—(CH₂)_(n)— starting from compounds of formula II-1 wherein Y1 is a halogen atom and compounds of formula III wherein A1-PG1 is a thiol group or an amino group (protected or not), respectively.

When A3 is a fluorine atom, compounds of formula IV-1 can react with a compound of formula V for which X is —CH₂—OH, in presence of an inorganic base such as sodium hydride or the like in a solvent such as tetrahydrofuran or N,N-dimethylformamide at a temperature ranging between −20° C. and 80° C., to generate compounds of formula VI-1 wherein R₄ is an ether group.

Alternatively, when A3 is a hydroxyl group, a Mitsunobu coupling between compounds of formula IV-1 and compounds of formula V for which X is —CH₂—OH can lead to the generation of compounds of formula IV-1 wherein R₄ is an ether group.

Additionally, when A3 is a hydroxyl group, compounds of formula IV-1 can react with a compound of formula V for which X is a halogen atom or a leaving group, in presence of an inorganic base such as sodium hydride or the like in a solvent such as tetrahydrofuran or N,N-dimethylformamide at a temperature ranging between −20° C. and 80° C., to generate compounds of formula VI-1 wherein R₄ is an ether group. When A3 is —CHO, compounds of formula IV-1 can react with compounds of formula V for which X is a phosphonium salt or a phosphonate via a Wittig or Horner-Wadsworth-Emmons reaction, respectively, to generate compounds of formula VI-1 for which R4 is a C₂-C₆-alkenyl group.

The Wittig reaction is the reaction of an aldehyde with a triphenyl phosphonium ylide to afford an alkene and triphenylphosphine oxide. The Wittig reagent is usually prepared from a phosphonium salt, which is, in turn, prepared by alkylation of triphenylphosphine with a benzyl halide. To form the Wittig reagent (benzyl ylide), the phosphonium salt is suspended in a solvent such as diethyl ether or tetrahydrofuran and a strong base such as n-butyl lithium is added. With simple ylides, the product is usually mainly the Z-isomer, although a lesser amount of the E-isomer also is often formed. If the reaction is performed in N,N-dimethylformamide in the presence of lithium or sodium iodide, the product is almost exclusively the Z-isomer. If the Z-isomer is the desired product, the Schlosser modification may be used.

Alternatively the Horner-Wadsworth-Emmons reaction produces predominantly E-alkenes. The Homer-Wadsworth-Emmons reaction is the condensation of stabilized phosphonate carbanions with aldehydes in presence of a base such as sodium hydride or sodium methylate in a solvent such as diethyl ether or tetrahydrofuran, between 0° C. and 50° C. In contrast to phosphonium ylides used in the Wittig reaction, phosphonate-stabilized carbanions are more nucleophilic and more basic. Diethyl benzylphosphonates can be easily prepared from readily available benzyl halides.

When A3 is —CHO, compounds of formula IV-1 can react with compounds of formula V for which X is —NH₂ or —NHE, E being an amino protecting group, via a reductive amination reaction, to generate compounds of formula VI-1 for which R₄ is an amine group. The reductive amination reaction between the amine and the aldehyde to form an intermediate imine is conducted in a solvent system allowing the removal of the formed water through physical or chemical means (e.g. distillation of the solvent-water azeotrope or presence of drying agents such as molecular sieves, magnesium sulfate or sodium sulfate). Such solvent is typically toluene, n-hexane, tetrahydrofuran, dichloromethane N,N-dimethylformamide, N,N-dimethylacetamide, acetonitrile, 1,2-dichloroethane or mixture of solvents such as methanol-1,2-dichloroethane. The reaction can be catalyzed by traces of acid (usually acetic acid). The intermediate imine is reduced subsequently or simultaneously with a suitable reducing agent (e.g. sodium borohydride, sodium cyanoborohydride, sodiumtriacetoxyborohydride; R. O. and M. K. Hutchins, Comprehensive Organic Synthesis, B. M. Trost, I. Fleming, Eds; Pergamon Press: New York (1991), vol. 8, p. 25-78) or through hydrogenation over a noble metal catalyst such as palladium on activated carbon. The reaction is usually carried out between −10° C. and 110° C., preferably between 0° C. and 60° C. The reaction can also be carried out in one pot. It can also be performed in protic solvents such as methanol or water in presence of a picoline-borane complex (Tetrahedron, 2004, 60, 7899).

When A3 is —CH₂OH, compounds of formula IV-1 can be converted to the corresponding halide, mesylate, tosylate, triflate compounds and further react with compounds of formula V for which X is a hydroxyl group, a thiol group or an amino group (protected or not) to generate compounds of formula VI-1 for which R4 is an ether, a thiol or amine group, respectively. The substitution reaction can proceed at a temperature between −20° C. and 100° C. in a dry aprotic solvent like dichloromethane, acetonitrile, N,N-dimethylformamide, dimethyl sulfoxide or tetrahydrofuran without or with an inorganic base such as potassium carbonate or cesium carbonate, or an organic base such as triethylamine or N,N-diisopropylethylamine.

When A3 is —COOH, compounds of formula IV-1 can react with compounds of formula V for which X is —NH₂ or —NHE, E being an amino protecting group, via a peptidic coupling reaction, to generate compounds of formula VI-1 for which R₄ is an amide group. The reaction takes place in the presence of an activating agent such as N,N′-dicyclohexylcarbodiimide or N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride, with the optional addition of 1-hydroxybenzotriazole. Other suitable coupling agents may be utilized such as, O-(7-azabenzotriazol-1-yl)-N,N,N,N′-tetramethyluronium hexafluorophosphate, 2-ethoxy-1-ethoxycarbonyl-1,2-dihydroquinoline, carbonyldiimidazole or diethylphosphorylcyanide. Optionally, a base like triethylamine, N,N-diisopropylethylamine or pyridine can be added to perform the coupling. The peptidic coupling is conducted at a temperature comprised between −20° C. and 80° C., in an inert solvent, preferably a dry aprotic solvent like dichloromethane, acetonitrile or N,N-dimethylformamide and chloroform. Alternatively, the carboxylic acid can be activated by conversion into its corresponding acid chloride or its corresponding activated ester, such as the N-hydroxysuccinimidyl ester (Org. Process Res. & Dev., 2002, 863) or the benzothiazolyl thioester (J. Antibiotics, 2000, 1071). The generated activated entity can react at a temperature comprised between −20° C. and 80° C. with compound of formula II-1 in an aprotic solvent like dichloromethane, chloroform, acetonitrile, N,N-dimethylformamide and tetrahydrofuran to generate compound of formula I-1. Optionally, a base like triethylamine, N,N-diisopropylethylamine, pyridine, sodium hydroxide, sodium carbonate, potassium carbonate can be added to perform the coupling.

For the generation of compounds of formula I-1, when Y2 is a halogen atom, a leaving group or —C(O)—CH₂—X, with X being a halogen atom, compounds of formula VI-1 can react with compounds of formula VII for which A4 is —NH₂ or —NHE, E being an amino protecting group, via a substitution reaction as previously described above, to generate compounds of formula I-1 wherein L2 is —(CH₂)_(o)— or —(CH₂)_(o)—C(O)—CH₂—, respectively.

Additionally, when Y2 is —CHO, compounds of formula VI-1 can react with compounds of formula VII for which A4 is —NH₂ or —NHE, E being an amino protecting group, via a reductive amination reaction as previously described above, to generate compounds of formula I-1 for which L2 is —(CH₂)_(p)—, wherein p is comprised between 1 and 4.

In certain cases, compounds of formula VI-1 for which Y2 is —CHO can be generated from the corresponding compounds for which Y2 is an ester group or a carboxylic acid function. The ester derivatives are further reduced into their corresponding alcohol. This reduction is performed with a reducing agent like boron or aluminium hydride reducing agent such as lithium aluminium hydride, lithium borohydride, sodium borohydride in a solvent such as tetrahydrofuran between −20° C. and 80° C. Alternatively, the ester function is hydrolyzed into its corresponding carboxylic acid using an alkali hydroxide such as sodium hydroxide, potassium hydroxide or lithium hydroxide in water or in a mixture of water with polar protic or aprotic organic solvents such as dioxane, tetrahydrofuran or methanol between −10° C. and 80° C. The resulting carboxylic acid is further reduced into the corresponding alcohol using a borane derivative such as borane-tetrahydrofuran complex in a solvent such as tetrahydrofuran between −10° C. and 80° C. The generated alcohol is then transformed into its corresponding aldehyde through oxidation under Swern, Dess Martin, Sarett or Corey-Kim conditions respectively. Further methods are described in Comprehensive Organic Transformations. A guide to functional Group Preparations; 2^(nd) Edition, R. C. Larock, Wiley-VC; New York, Chichester, Weinheim, Brisbane, Singapore, Toronto, 1999. Section aldehydes and ketones, p. 1235-1236 and 1238-1246.

When Y2 is —COOH, compounds of formula VI-1 can react with compounds of formula VII for which A4 is —NH₂ or —NHE, E being an amino protecting group, via a peptidic coupling reaction as previously described above, to generate compounds of formula I-1 wherein L2 is —(CH₂)_(o)—C(O)—.

Alternatively, when Y2 is —NH-PG2, PG2 being an amino protecting group, the protecting group can first be removed under standard conditions. For example the benzyl carbamates are deprotected by hydrogenolysis over a noble metal catalyst (e.g. palladium or palladium hydroxide on activated carbon). The Boc group is removed under acidic conditions such as hydrochloric acid in an organic solvent such as methanol, dioxane or ethyl acetate, or trifluoroacetic acid neat or diluted in a solvent such as dichloromethane. The Alloc group is removed in presence of a palladium salt such as palladium acetate or tetrakis(triphenylphosphine)palladium(0) and an allyl cation scavenger such as morpholine, pyrrolidine, dimedone or tributylstannane between 0° C. and 70° C. in a solvent such as tetrahydrofuran. The N-benzyl protected amines are deprotected by hydrogenolysis over a noble metal catalyst (e.g. palladium hydroxide on activated carbon). The Fmoc protecting group is removed under mild basic conditions such as diluted morpholine or piperidine in N,N-dimethylformamide or acetonitrile. Further general methods to remove amine protecting groups have been described in Protective Groups in Organic Synthesis, 3^(rd) Edition, by T. W. Greene and P. G. M. Wuts, published by John Wiley & Sons, 1999.

The corresponding free amine can then react with compounds of formula VII for which A4 is —CH₂—X or —CHO via a substitution or a reductive amination, respectively, to generate compounds of formula I-1 wherein L2 is —(CH₂)_(o)—.

The corresponding free amine can also react with compounds of formula VII for which A4 is —COOH via a peptidic coupling, to generate compounds of formula I-1 wherein L2 is —(CH₂)_(o)—.

Alternatively, the amino protecting group PG2 can also be removed only after the substitution, the reductive amination or the pcptidic coupling reactions, following standard procedure described above.

For the generation of compounds of formula I-1 for which L2 is —(CH₂)_(o)—, compounds of formula VI-1 wherein Y2 is a hydroxyl group, can be converted to the corresponding halide, mesylatc, tosylatc or triflatc compound and react with compounds of formula VII for which A4 is —NH₂ or —NHE, E being an amino protecting group, via a substitution reaction as previously described above.

In addition and following substitution reaction conditions described above, compounds of formula I-1 for which L2 is —(CH₂)_(o)—O—(CH₂)_(q)— can be obtained by reacting compounds of formula VI-1 wherein Y2 is a hydroxyl group with compounds of formula VII for which A4 is —(CH₂)—X, X being a halogen atom or a leaving group and q being comprised between 1 and 4.

Finally, compounds of formulae VI-1, I-1 and I-2 for which L1 is —(CH₂)_(m)—SO—(CH₂)_(n)— or —(CH₂)_(m)—SO₂—(CH₂)_(n)— can be generated by oxidation of compounds of formulae IV-1, VI-1 and I-1, respectively, for which L1 is —(CH₂)_(m)—S—(CH₂)_(n)— in presence of a peroxide such as dihydrogen peroxide or meta-chloroperbenzoic acid or the like in a solvent such as dichloromethane, acetonitrile or ethyl acetate at a temperature ranging between −20° C. and 60° C.

In certain cases, when A3 or Y2 are hydroxyl groups, protection of this function is required and is carried out under standard conditions. For example the benzyl or the allyl groups are introduced with an alkaline solution of benzyl or allyl halide, respectively; the tetrahydropyranyl group is introduced with dihydropyran under acidic conditions; the hydroxyl groups are protected as silyl ethers by reacting with the required silyl chloride reagent in presence of a base such as imidazole or pyridine. Further general methods to introduce hydroxyl protecting groups have been described in Protective Groups in Organic Synthesis, 3^(rd) Edition, by T. W. Greene and P. G. M. Wuts, published by John Wiley & Sons, 1999.

Such hydroxyl protecting groups can be removed at any convenient step of the process. The benzyl group is removed by hydrogenolysis over a noble metal catalyst (e.g. palladium or palladium hydroxide on activated carbon); the tetrahydropyranyl group is removed in presence of para-toluenesulfonic acid with a pH of 3, between 40° C. and 70° C. in a solvent such as methanol; the silyl ether groups are removed either using fluoride anion sources such as tetra-n-butylammonium fluoride in a solvent such as tetrahydrofuran or N,N-dimethylformamide between 0° C. and 40° C. or in hydrofluoric acid in acetonitrile between 0° C. and 40° C. or using acidic conditions such as acetic acid in tetrahydrofuran-methanol or hydrochloric acid in methanol. Further general methods to remove hydroxyl protecting groups have been described in Protective Groups in Organic Synthesis, 3^(rd) Edition, by T. W. Greene and P. G. M. Wuts, published by John Wiley & Sons, 1999. In Scheme 1, the amino protecting groups PG1, PG2 and E can be removed at any convenient step of the process.

The compounds of formula I wherein L1 is —O—(CH₂)_(n)—, —S—(CH₂)_(n)—, —NH—(CH₂)_(n)—, —SO—(CH₂)_(n)— or —SO₂—(CH₂)_(n)—, with n being 0, 1, 2 or 3 (within the limits defined by the claims), can be obtained as summarized in Scheme 2.

In Scheme 2, all the symbols have the same meanings as previously described in process (b).

Compounds of formula IV-2 wherein L1 is —O—(CH₂)_(n)—, —S—(CH₂)_(n)— or —NH—(CH₂)_(n)— can be obtained via a substitution reaction between compounds of formula VIII for which -A1-PG1 is —OH, —SH, —NH₂ or NHE, respectively, E being an amino protecting group, with compounds of formula IX, following procedures previously described above in Scheme 1.

Alternatively, compounds of formula IV-2 wherein L1 is —O—(CH₂)_(n)—, can be obtained from compounds of formula VIII wherein -A1-PG1 is —OH via a Mitsunobu coupling (as reviewed in O. Mitsunobu, Synthesis 1981, 1) with compounds of formula IX for which Y is a hydroxyl group, following procedures previously described above in Scheme 1.

Further conversion of compounds of formula IV-2 into compounds of formula I-3 and I-4 is performed following methods described above in Scheme 1 for the preparation of compounds of formula I-1 and 1-2.

In Scheme 2, the amino protecting groups PG1, PG2 and E can be removed at any convenient step of the process.

The compounds of formula I wherein L1 is —CH═CH—(CH₂)_(m)— (double bond Z, E or Z/E) or —(CH₂)_(m+2)—, with m being 0 or 1, can be obtained as summarized in Scheme 3.

In Scheme 3, all the symbols have the same meanings as previously described in process (c).

Compounds of formula IV-3 wherein L1 is —CH═CH—(CH₂)_(m)— (double bond Z, E or Z/E), with m being 0 or 1, can be obtained via a Wittig or Horner-Wadsworth-Emmons reaction between compounds of formula II-2 for which X is a phosphonium salt or a phosphonate and compounds of formula X, following procedures previously described above in Scheme 1.

Further conversion of compounds of formula IV-3 into compounds of formula I-5 is performed following methods described above in Scheme 1 for the preparation of compounds of formula I-1.

Compounds of formulae IV-2, VI-2 and I-5 for which L1 is —CH═CH—(CH₂)_(m)— (double bond Z, E or Z/E), with m being 0 or 1, can also be converted into compounds of formulae VI-2, I-5 and 1-6, respectively, for which L1 is or —(CH₂)_(m+2)— via hydrogenolysis over a noble metal catalyst (palladium or palladium hydroxide on activated carbon; Chem. Eur. J., 1999, 5, 1055).

In Scheme 3, the amino protecting groups PG1, PG2 and E can be removed at any convenient step of the process.

The compounds of formula I wherein L1 is —C≡C— can be obtained as summarized in Scheme 4.

In Scheme 4, all the symbols have the same meanings as previously described in process (d). In Scheme 4, compounds of formula XII are first converted into compounds of formula XIII, via a Sonogashira cross-coupling reaction with the commercially available trimethylsilylacetylene, followed by a desylilation step.

The Sonogashira reaction is a cross-coupling of terminal alkynes with aryl or vinyl halides that is carried out in presence of a palladium catalyst such as palladium(II) acetate, palladium(II) chloride, tetrakis(triphenylphosphine)palladium(0) or the like, a copper(I) cocatalyst such as copper(I) iodide and an amine base such as diethylamine, triethylamine, diisoppropylamine, diisopropylethylamine, N-butylamine or the like in an inert solvent such as tetrahydrofuran or N,N-dimethylformamide, at a temperature comprised between 0° C. and 120° C. Other bases such as potassium carbonate or cesium carbonate are occasionally used.

Desilylation is then carried out under standard conditions in presence of a base such as potassium carbonate in a solvent such as methanol, or in presence of tetrabutylammonium fluoride in tetrahydrofuran. Further general methods to remove the trimethylsilyl group have been described in Protective Groups in Organic Synthesis, 3rd Edition, by T. W. Greene and P. G. M. Wuts, published by John Wiley & Sons, 1999.

Compounds of formula IV-4 are then obtained via a second Sonogashira cross-coupling reaction between compounds of formula XI and the generated compounds of formula XIII.

Further conversion of compounds of formula IV-4 into compounds of formula I-7 is performed following methods described above in Scheme 1 for the preparation of compounds of formula I-1.

In Scheme 4, the amino protecting groups PG1, PG2 and E can be removed at any convenient step of the process.

The compounds of formula I wherein L1 is —(CH₂)_(m)—NH—C(O)—, with m being 0 or 1, can be obtained as summarized in Scheme 5.

In Scheme 5, all the symbols have the same meanings as previously described in process (e).

Compounds of formula IV-5 can be prepared via a peptidic coupling reaction between compounds of formula XIV and compounds of formula XV, following procedures previously described above in Scheme 1.

Further conversion of compounds of formula IV-5 into compounds of formula I-8 is performed following methods described above in Scheme 1 for the preparation of compounds of formula I-1.

In Scheme 5, the amino protecting groups PG1, PG2 and E can be removed at any convenient step of the process.

The compounds of formula I wherein L1 is —C(O)—NH—(CH₂)_(n)— or —SO₂—NH—(CH₂)_(n)— with n being 0 or 1, can be obtained as summarized in Scheme 6.

In Scheme 6, all the symbols have the same meanings as previously described in process (f).

When A1 is —COOH, compounds of formula IV-6 can be prepared via a peptidic coupling reaction between compounds of formula XVI and compounds of formula XVII, following procedures previously described above in Scheme 1.

When A1 is —SO₂C1, compounds of formula IV-6 can be prepared following substitution reaction conditions previously described above in Scheme 1.

Further conversion of compounds of formula IV-6 into compounds of formula I-9 is performed following methods described above in Scheme 1 for the preparation of compounds of formula I-1.

In Scheme 6, the amino protecting groups PG1, PG2 and E can be removed at any convenient step of the process.

The compounds of formula I wherein L1 is absent or is —O— can be obtained as summarized in Scheme 7.

In Scheme 7, all the symbols have the same meanings as previously described in process (g).

When A1 is —OH, compounds of formula XVIII can react with compounds of formula XIX for which A4 is a fluorine atom, under basic conditions in presence of potassium carbonate, cesium carbonate or the like in a solvent such as N,N-dimethylformamide, at a temperature between 20° C. and 120° C., to generate compounds of formula IV-7 wherein L1 is —O—.

Alternatively, compounds of formula IV-7 wherein L1 is —O— can be obtained by reacting compounds of formula XVIII for which A1 is —OH with compounds of formula XIX for which A4 is a boronic acid or a boronic ester in presence of copper(II) acetate and triethylamine in a solvent such as dichloromethane under dry conditions and at a temperature between 0° C. and 80° C.

When A1 is a halogen atom or a triflate, compounds of formula XVIII can react with compounds of formula XIX for which A4 is a boronic acid, a boronic ester or —SnBu₃ via a Suzuki or a Stille cross coupling reaction, to generate compounds of formula VI-7 wherein L1 is absent.

The Suzuki reaction is a palladium-catalyzed cross coupling between organoboronic acids and aryl or vinyl halides or triflates. Typical catalysts include palladium(II) acetate, tetrakis(triphenylphosphine)palladium(0), bis(triphenylphosphine)palladium(II) dichloride and [1,1′bis(diphenylphosphino)ferrocene]dichloropalladium(II). The reaction can be carried out in a variety of organic solvents including toluene, tetrahydrofuran, dioxane, 1,2-dichloroethane, N,N-dimethylformamide, dimethylsulfoxide and acetonitrile, aqueous solvents and under biphasic conditions. Reactions are typically run from room temperature to 150° C. Additives such as cesium fluoride, potassium fluoride, potassium hydroxide or sodium ethylate frequently accelerate the coupling. Potassium trifluoroborates and organoboranes or boronate esters may be used in place of boronic acids. Although there are numerous components in the Suzuki reaction such as the particular palladium catalyst, the ligand, additives, solvent, temperature, numerous protocols have been identified. One skilled in the art will be able to identify a satisfactory protocol without undue experimentation.

Alternatively the Stille coupling is a versatile palladium-catalyzed coupling reaction between organostannanes and halides or pseudohalides. In comparison to the Suzuki reaction, the main drawback is the toxicity of the tin compounds used, and their low polarity, which makes them poorly soluble in water.

Further conversion of compounds of formula IV-7 into compounds of formula I-10 is performed following methods described above in Scheme 1 for the preparation of compounds of formula I-1. In Scheme 7, the amino protecting groups PG1, PG2 and E can be removed at any convenient step of the process.

Finally, some compounds of formula I present a quaternary amine. These compounds can be obtained by reacting a C₁-C₆-alkyl halide or the corresponding mesylate, tosylate or triflate with any compounds of formula I or VI for which a free amine is present, in presence of a base such as sodium hydrogen carbonate, potassium carbonate, cesium carbonate, sodium hydroxide, triethylamine, in a variety of organic solvents including methanol, acetonitrile, acetone, dichloromethane and N,N-dimethylformamide, aqueous solvents and under biphasic conditions. Reactions are typically run from 0° C. to 150° C.

Unless otherwise stated the required starting compounds of formula II, III, V, VII to XII, XIV to XIX are prepared following or adapting procedures described in the scientific literature.

When an optically active form of a compound of the invention is required, it may be obtained by carrying out one of the above procedures using a pure enantiomer or diastercomer as a starting material, or by resolution of a mixture of the enantiomers or diastereomers of the final product or intermediate using a standard procedure. The resolution of enantiomers may be achieved by chromatography on a chiral stationary phase, such as REGIS PIRKLE COVALENT (R—R) WHELK-02, 10 μm, 100 Å, 250×21.1 mm column. Alternatively, resolution of stereoisomers may be obtained by preparation and selective crystallization of a diastereomeric salt of a chiral intermediate or chiral product with a chiral acid, such as camphorsulfonic acid.

Alternatively a method of stereoselective synthesis may be employed, for example by using a chiral variant of a protecting group, a chiral catalyst or a chiral reagent where appropriate in the reaction sequence. Enzymatic techniques may also be used for the preparation of optically active compounds and/or intermediates.

The invention will now be described by way of non-limiting examples.

Proton NMR spectra are recorded on a Brucker 400 MHz spectrometer. Chemical shifts (δ) are reported in ppm relative to Me₄Si as internal standard, and J values are in Hertz (Hz). Each peak is denoted as a broad singlet (br), singlet (s), doublet (d), triplet (t), quadruplet (q), doublet of doublets (dd), triplet of doublets (td) or multiplet (m).

Mass spectra are generated using a q-Tof Ultima (Waters AG) mass spectrometer in the positive ESI mode.

The system is equipped with the standard Lockspray interface;

each intermediate is purified to the standard required for the subsequent stage and is characterized in sufficient detail to confirm that the assigned structure is correct;

analytical and preparative HPLC on non-chiral phases are performed using RP-C18 based columns; the following abbreviations may be used:

Biological Examples Efflux Inhibition Assay:

In vitro efflux-pump inhibition was measured with P. aeruginosa based on Alamar Blue accumulation following a published procedure (F. Vidal-Aroca et al. 2009. J. Microbiol. Methods 79: 232-237). P. aeruginosa PAO1 was grown on Miller-Hinton agar plates. Bacteria were resuspended in Dulbecco's phosphate buffered saline to OD625=1. Assays were performed in 96-well microtiter plates. Each well contained 100 μL assay mixture with 84 μL bacteria suspension, 5 μl succinic acid 40 mM, 10 μL Alamar Blue (Biosource DAL1100) and 1 μL test compound in DMSO. Fluorescence was measured every 5 minutes for 1 h with a Spectramax microtiter plate reader (ex at 530 nm, em at 590 nm).

Inhibition of efflux pumps caused increased accumulation of Alamar Blue compared to controls without inhibitor (i.e. uninhibited control). Results were expressed as relative fluorescence intensity (% of uninhibited control). Efflux inhibition caused increased relative fluorescence.

Antibacterial Activity in Combination with Minocycline or with Linezolid:

Inhibition of growth was measured with E. coli ATCC25922 and P. aeruginosa PAO1 in a 96-well plate format. Cation-adjusted Miller-Hinton broth (caMHB) was inoculated with an overnight culture and incubated at 37° C. on a shaker until OD625 reached 0.6 to 0.7. Density was adjusted to OD600=0.5 by addition of caMHB. 35 μL of the suspension were diluted to 35 mL with caMHB and supplemented with minocycline at the subinhibitory doses of 0.25 μg/mL for E. coli and 8 μg/mL for P. aeruginosa or with linezolid at the subinhibitory dose of 128 μg/mL for E. coli and P. aeruginosa. Each well contained 1 μL of test compound in 100 μL caMHB with minocycline or with linczolid.

Plates were incubated at 37° C. on a plate shaker. OD625 was measured at 1 h, 6 h, and at 23 h.

The difference between OD at 23 h and at 1 h was taken as measure for cell density and compared to controls without inhibitor (i.e. uninhibited control). Results were expressed as residual growth (% of uninhibited control). Enhancement of minocycline or linezolid activity caused reduced residual growth.
